Guardian's Return

 is a quest in Tyranny.

Synopsis
The Bronze Brotherhood have staged a raid on Lethian's Crossing. Help drive them from the settlement.

Walkthrough

 * The quest has a minor variation depending on who holds the crossing. If the Brotherhood does, a member will approach you pleading for help (you can attack to claim the settlement) and later you will witness Raetommon killing Ring-Dropper Ceratha in the Moonrise Market. You also won't fight any Brotherhood members until the last group of four. Otherwise:
 * Straightforward. Sweep through the Crossing and kill the Bronze Brotherhood members. There are two groups in each district, for a total of about 12 fighters (excluding the ones who attack you at the exit from the oldwalls). Saber, the commander on the attack, is in the Moonrise district, ground level.
 * After disposing of them, go to Eldian's House to check on Eldian. You'll see Raetommon flee. With Athletics 55 you can throw a rock at him. Otherwise, make a rude gesture or glare silently.
 * Give chase. You'll find him holding Zdenya hostage. He'll flee, using his men to delay you. Go back to Eldian to unlock Twin Rivers and Deserter's March and start In the Shadow of the Oldwalls.
